Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
General Information: Notes
The instrument cluster contains an electronic speedometer, tachometer, liquid crystal (LCD) displays for odometer, trip odometer/clock, as well as analog coolant temperature and fuel level gauges. Control and warning lamps are situated within and between the speedometer and tachometer, as well as an LCD gear indicator display.
The instrument cluster is controlled by an internal microprocessor with On Board Diagnostic (OBD) capability. If malfunctions occur in monitored sensors and components, Diagnostic Trouble Codes (DTC) will be stored in memory together with an indication of malfunction type. A maximum of 4 DTCs can be stored simultaneously.
Sporadic malfunctions (indicated in the readout by "SP") are automatically cancelled if not repeated in the next 50 engine start cycles.
Before performing any troubleshooting or inspection, always begin by checking for DTCs using the OBD program. DTCs stored in memory are retrieved/checked with either the VAG 1551/1552 Scan Tool (ST) or VAS 5051 Vehicle Diagnostic Testing and Information System in operating mode "Vehicle Self-Diagnosis".
For OBD purposes, the instrument cluster counts one start cycle whenever the ignition is switched on longer than 5 min. and a minimum speed of 30 km/h (18.5 mp/h ) is exceeded.
